Anna Faris explains why she never saw Chris Pratt as her best friend

Anna Faris has told how she "never bought" into the idea that husbands should be their wives' best friends - as she admitted she never counted Chris Pratt as hers.

The couple, who were married for eight years, announced their separation in a join social media statement last month. And now the actress has opened up about some of the lessons she learned from her relationship with the Jurassic World star in her new book, Unqualified.  Including the fact that he never was, and she thought he never should have been, her best friend. An excerpt shared with Cosmopolitan explains:

"I was once told that I didn’t need a tight group of girlfriends because Chris should be my best friend. But I never bought that. "The idea of your mate being your best friend — it’s overhyped. I really believe that your partner serves one purpose and each friend serves another. "There’s the friend you confess things to and the friend with whom you do the listening. "Or this is the person I talk to when I’m feeling lonely and sad, this is the person I talk to about work sh*t, and this is the friend I’m still in touch with because we grew up together."

And while the mum of one said she previously considered herself "a guys' girl", she had learned to appreciate the important value of female friendships over time. She continued:

"Today, I’m lucky to have a handful of women I count as confidantes. "Among them, Allison Janney, my costar on Mom, Meghan, a friend from my hometown of Edmonds, Washington, and Kate, a dear childhood friend who I probably have nothing in common with anymore — at least from an outsider’s perspective — but who totally gets me because ... history."

The Mom star went on to explain her problem with the idea of "best friends" overall - adding that the idea is "messed up". She continued:

“It puts so much pressure on any one person, when I truly believe it’s okay to have intimacy with different people in different ways. "And ranking your friends? It just shouldn’t happen, at least not beyond grade school.”
